Application September 28, 1937, Serial No. 168,119

1 Claim. (Cl- 202-") This invention relates to the denaturing or ethyl alcohol, and to alcohol so denatured.

It is an object 01' my invention to provide a denaturant which will render ethyl alcohol containing it unfit for use as a beverage, which cannot be economically removed from the alcohol by any known methods, which will not render the alcohol unfit for industrial uses in which denatured alcohol has customarily been employed, and which will be free from methanol. Other objects will hereinafter appear.

I have discovered that diphenyl ether,

CsHs.O.CcHs

is an eflective denaturant for alcohol. In denaturing ethyl alcohol with my novel denaturant, I may use from 0.5 to 5 parts of diphenyl ether,

or even more, per 100 parts of 95% alcohol. Diphen-yl ether may be used alone in denaturing, or it may be used in conjunction withdenaturing materials derived from the destructive distillation of hardwood, such as those which are described in my U. 8. Patents Nos. 1,975,090; 1,975,- 091 and 1,975,092. Likewise, it may be used in conjunction with amino compounds, or with any other denaturants with which it may be found to be compatible.

What I claim as my invention and desire to be secured by Letters Patent 0! the United States is:

Industrial ethyl alcohol denatured with 0.5 to 5 parts of diphenyl ether, as an essential denaturing' element, per 100 parts of 95% ethyl alcohol.
